The human voice communicates emotion through two different types of vocalizations: nonverbal vocalizations (brief non-linguistic sounds like laughs) and speech prosody (tone of voice). Research examining recognizability of emotions from the voice has mostly focused on either nonverbal vocalizations or speech prosody, and included few categories of positive emotions. In two preregistered experiments

While much is known about how negative emotions are expressed in different modalities, our understanding of the nonverbal expressions of positive emotions remains limited. In the present research, we draw upon disparate lines of theoretical and empirical work on positive emotions, and systematically examine which channels are thought to be used for expressing four positive emotions: feeling moved,

Since Darwin’s (1872) publication of The Expression of the Emotions in Man and Animals, emotion researchers have made tremendous progress in understanding the function, structure, and significance of emotion. Yet, the bulk of this work has focused squarely on the face. Recent research has shown the importance of augmenting facial expression research with a focus on other modalities, and carefully attending

This article unpacks the basic mechanisms by which paralinguistic features communicated through the voice can affect evaluative judgments and persuasion. Special emphasis is placed on exploring the rapidly emerging literature on vocal features linked to appraisals of confidence (e.g., vocal pitch, intonation, speech rate, loudness, etc.), and their subsequent impact on information processing and meta-cognitive

Past research has largely focused on how emotional expressions provide information about the speaker’s emotional state, but has generally neglected vocal affect’s influence over communication effectiveness. This is surprising given that other nonverbal behaviors often influence communication between individuals. In the present theory paper, we develop a novel perspective called the Contextual Influences

For many people, emotions are frequently expressed in the context of communication with their God. The practice of prayer is clearly embodied and affords the study of full body expressions of emotions in a relevant context. Surprisingly uncharacterized in empirical scientific research, we document full body postures representing prayers in different emotional registers (i.e., prayer, worship, praise

Although emotion expressions are typically dynamic and include the whole person, much emotion recognition research uses static, posed facial expressions. In this study, we created a stimulus set of dynamic, naturalistic expressions drawn from professional tennis matches to determine whether movement would result in better recognition. We examined participants’ judgments of static versus dynamic expressions

We conducted two studies to explore the potential meanings associated with the “heartfelt” gesture, which involves placing one’s hand with a flat palm in the center of the chest. In Study 1, we approached 176 participants in various social settings and asked them to recall an example of the gesture and the emotion they associated with its use. Although shock and surprise emerged as important themes

Age-related deficits are often observed in emotion categorization tasks that include negative emotional expressions like anger, fear, and sadness. Stimulus characteristics such as facial cue salience and gaze direction can facilitate or hinder facial emotion perception. Using two emotion discrimination tasks, the current study investigated how older and younger adults categorize emotion in faces with

Past research has demonstrated that children understand distinct emotion concepts and can accurately recognize facial expressions of distinct emotions by a young age, but few studies have assessed the age at which children develop the ability to recognize bodily expressions of distinct emotions. The current pre-registered research is the largest study to date (N = 552) examining the age at which children

Two paradigms measuring teaching effectiveness in higher education—one focusing on instructional behaviors (SET), and the other, on teachers' nonverbal and verbal immediacy (NVI-VI)—have been estranged from each other for decades despite their common focus on teaching effectiveness. To juxtapose the two paradigms, both SET and NVI-VI questionnaires were administered at separate times in courses taught

The aim of this study was to investigate the effect of conversational role (speaking versus listening) and conversational agreement (agreement versus disagreement) on eye gaze toward the interlocutor in the context of controversial, political conversations. Previous studies have only examined these variables independently of one another and typically not in face-to-face conversations. Participants

People tend to assign higher attractiveness to an individual viewed from the back than head on. This tendency is pronounced when males rate the attractiveness of women. This study investigated reasons for the previously observed gender difference in this bias, focusing on the social relationship between raters (participants) and rated models (stimuli). To manipulate the assumed social relationship

Emotions are expressed by physical expressions such as body posture. Physical cues play a crucial role in recognizing emotional states. We hypothesized that bodily expressions are stored in long-term memory in association with emotion and that such memory representation, knowledge of emotion, enables us to recognize mental states as a certain emotion. The present study focused on sadness as the target

The current research tested how expectations and mimicry in an interracial interaction influence positive and negative affect. Existing research suggests that individuals do not expect mimicry, a behavior that should otherwise engender liking, in interracial interactions. Although past research has focused on how Whites’ expectations for interracial interactions leads to poor experiences, the present

Children show sex differences in early speech development, with girls producing a greater number and variety of words at an earlier age than boys (Berglund et al. in Scand J Psychol 46(6): 485–491, 2005)—a pattern that also becomes evident in gesture (Butterworth and Morisette in J Reprod Infant Psychol 14(3): 219–231, 1996). Importantly, parents show variability in how they produce speech when interacting

The adult voice is a strong bio-social marker for masculinity and femininity. In this study we investigated whether children make gender stereotypical judgments about adults’ occupational competence on the basis of their voice. Forty-eight 8- to 10- year olds were asked to rate the competence of adult voices that varied in vocal masculinity (by artificially manipulating voice pitch) and were randomly

Emotion decoding competence can be addressed in different ways. In this study, clinical psychology, nursing, or social work students narrated a 2.5–3 min story about a self-experienced emotional event and also listened to another student’s story. Participants were video recorded during the session. Participants then annotated their own recordings regarding their own thoughts and feelings, and they

Nonverbal markers of childhood trauma have been identified in the literature. Yet, the relationship between childhood trauma and the voice is still largely unexplored. We report preliminary findings from a study (N = 48) that investigated whether self-reported childhood trauma is related to acoustic measures on sustained phonation before and after childhood trauma recall. Childhood trauma and minimization/denial

Physical attractiveness plays a central role in psychosocial experiences. One of the top research priorities has been to identify factors affecting perceptions of physical attractiveness (PPA). Recent work suggests PPA derives from different sources (e.g., target, perceiver, stimulus type). Although smiles in particular are believed to enhance PPA, support has been surprisingly limited. This study

In this study, we investigated the cognitive processes and nonverbal cues used to detect altruism in three experiments based on a zero-acquaintance video presentation paradigm. Cognitive mechanisms of altruism detection are thought to have evolved in humans to prevent subtle cheating. Several studies have demonstrated that people can correctly estimate levels of altruism in others. In this study, we

Emotional tears have been proposed to serve as a signal of distress, appeasement, and helplessness, which promotes prosocial responses in observers. They may also facilitate the perception of sadness. A still unanswered question is what information tears convey about emotional states when they are combined with different muscular facial expressions. The current study evaluated three hypotheses: Tears

People are accurate at classifying emotions from facial expressions but much poorer at determining if such expressions are spontaneously felt or deliberately posed. We explored if the method used by senders to produce an expression influences the decoder’s ability to discriminate authenticity, drawing inspiration from two well-known acting techniques: the Stanislavski (internal) and Mimic method (external)

Thin slices, or excerpts of behavior, are commonly used by researchers to represent behaviors in their full stimulus. The present study asked how slices of different lengths and locations, as well as different measurement methodologies, influence correlations between the measured behavior and different variables (predictive validity). We collected self-rated, perceiver-rated, and objectively measured

In the fields of face recognition and voice recognition, a growing literature now suggests that the ability to recognize an individual despite changes from one instance to the next is a considerable challenge. The present paper reports on one experiment in the voice domain designed to determine whether a change in the mere style of speech may result in a measurable difficulty when trying to discriminate

The left-cradling bias is the tendency to cradle an infant on the left side, regardless of the individuals’ handedness, culture or ethnicity. Many studies revealed associations between socio-emotional variables and the left-side bias, suggesting that this asymmetry might be considered as a proxy of the emotional attunement between the cradling and the cradled individuals. In this study we examined

This paper investigates the paradoxical finding that physical pain in certain social situations makes people smile. A number of models have been proposed to explain emotional behaviour, and we tested some important predictions they make regarding the mental antecedents and cognitive properties that could characterize such distress smiles, specifically ones that occur in informal and non-serious social

Nonverbal pain cues such as facial expressions, are useful in the systematic assessment of pain in people with dementia who have severe limitations in their ability to communicate. Nonetheless, the extent to which observers rely on specific pain-related facial responses (e.g., eye movements, frowning) when judging pain remains unclear. Observers viewed three types of videos of patients expressing pain

The present research attempted to test how skilled people are at predicting perceptual-motor performance of professional darts players based on short observations of pre-performance nonverbal behavior. In four thin-slices experiments (total N = 490) we randomly sampled stimulus material from the 2017 World Championships of Darts showing short video recordings of the players immediately before throwing

The significance of the body-mind link and the contribution of nonverbal communication in the context of psychotherapy is enjoying increased interest. Yet, the main measurements used in psychotherapy studies rely mostly on verbal measures, missing other channels of communication that would allow rich and implicit, nonverbal information. The present study is a first step toward using the mirror game

On 11 March 2020, the World Health Organization officially declared COVID-19 a pandemic. The new physical distancing rules have had many consequences, some of which are felt throughout the justice system. Courts across the world limited their operations. Nonetheless, given that justice delayed is justice denied, many jurisdictions have turned to technologies for urgent matters. This paper offers an

The aim of the present work is to investigate the facilitating effect of vocal emotional intonation on the evolution of the following processes involved in language: (a) identifying and producing phonemes, (b) processing compositional rules underlying vocal utterances, and (c) associating vocal utterances with meanings. To this end, firstly, I examine research on the presence of these abilities in

Nonverbal vocal aspects of communication, often related to affective states, are crucial to social interactions not only for animals but also for humans during early infancy, as well as being one of the pillars of human language development and acquisition. The thread that binds together the contributions to this Special Issue is the analysis of nonverbal vocal communication during development, both

Although evidence is available about preterm newborns’ spontaneous behavioral repertoire during the first weeks of life in the neonatal intensive care unit (NICU), studies on infant behavioral responses to external social stimuli are scarce. The main aim of this study was to analyze preterm infant behaviors in response to the maternal voice, speaking or singing, in the NICU, compared with a control

Preterm infants’ behavioral state and physiological parameters are affected by environmental noise and adult voices. Only a handful of studies have explored the effects of direct maternal vocal communication on preterm infants’ autonomous nervous system responses. Furthermore, to our knowledge, no study to date has investigated the effect of the father’s voice on preterm infant’s behaviors and physiological

Eye contact is a fundamental aspect of nonverbal communication and therefore important for understanding human interaction. Eye contact has been the subject of research in many disciplines, including communication sciences, social psychology, and psychiatry, and a variety of techniques have been used to measure it. The choice of measurement method has consequences for research outcomes and their interpretation

Interpersonal tactile stroking stimulation activates different peripheral nerve fibers, especially C-tactile afferents, which encode pleasant and erotic sensations. Hence, humans typically stroke close interaction partners with velocities that are suited to stimulate C-tactile afferents in the touch receivers’ skin. We aim to replicate this finding and we furthermore hypothesized that humans adjust

Human preverbal development refers to the period of steadily increasing vocal capacities until the emergence of a child’s first meaningful words. Over the last decades, research has intensively focused on preverbal behavior in typical development. Preverbal vocal patterns have been phonetically classified and acoustically characterized. More recently, specific preverbal phenomena were discussed to

People often make inferences about others from the physical appearance and social group characteristics revealed through their photographs. Because physicians’ photographs are routinely displayed to prospective patients in websites, print media, and direct mail, it is possible that this practice triggers conscious or unconscious biases in potential patients. We investigated first impressions of physicians

This study investigated age differences and similarities in younger and older women’s ability to accurately judge others’ emotions, personality, and rapport, collectively referred to as interpersonal accuracy (IPA). A sample of 124 young (ages 18–22) and 94 older women (ages 60–90) completed four different IPA tasks: two emotion perception tasks using posed stimuli, and two interaction-based tasks

Emoji faces are ubiquitous and integrated into most people’s everyday (nonverbal) vernacular. Yet, we know little about how people interpret these characters in terms of their emotional content. Do people agree that an emoji face represents an individual emotion and that it is unique to a specific emotion? Are such representations similar across electronic platforms? The present study took a theoretical

People rapidly form impressions of others based on their gender. Women tend to be liked more than men but men tend to be regarded as more powerful. However, a person’s nonverbal behavior has the potential to confirm or override these stereotypical impressions. Specifically, expansive, open body postures (e.g., based on widespread limbs) tend to convey high power compared to contracted, closed body

Crying is a uniquely human behavior, the functions of which are at present not completely understood. We hypothesized that tears promote the perception of morally relevant traits and states such as sincerity, honesty, and remorse, which facilitate social bonding and we, therefore, predicted that tears would reduce the punishments proposed for transgressors. Participants were exposed to photographs

Human screams have been suggested to comprise a salient and readily identified call type, yet few studies have explored the degree to which people agree on what constitutes a scream, and the defining acoustic structure of screams has not been fully determined. In this study, participants listened to 75 human vocal sounds, representing both a broad acoustical range and array of emotional contexts, and

This review explores spontaneous mimicry in the context of three questions. The first question concerns the role of spontaneous mimicry in processing conceptual information. The second question concerns the debate whether spontaneous mimicry is driven by simple associative processes or reflects higher-order processes such as goals, intentions, and social context. The third question addresses the implications

Observing nonverbal signals being directed toward unfamiliar individuals is known to influence attitudes and behavior toward those individuals. Specifically, observing biased nonverbal signals in favor of one individual over another can produce nonverbal signal-consistent attitudes among preschool children. Research has also shown that people have a tendency to mimic the behavior of others. The phenomenon

Nonverbal synchrony (NVS) of a patient’s and therapist’s body parts during a therapy session has been linked with therapeutic alliance. However, the link between NVS of face parts with therapeutic alliance remains unclear. The clarification of this link is important in understanding NVS. Accordingly, we used a video imaging technique to provide quantitative evidence of this link. The 55 participants

The study of mimicry has a rich history of investigation in nonverbal communication research, although the area has struggled with inconsistent operationalizations of the construct. The Special Issue on Nonconscious Mimicry includes empirical, methodological and theoretical innovations, and provides guidance about future directions. This introduction highlights a number of emerging themes in this Special

Conversation between two people involves subtle nonverbal coordination in addition to speech. However, the precise parameters and timing of this coordination remain unclear, which limits our ability to theorize about the neural and cognitive mechanisms of social coordination. In particular, it is unclear if conversation is dominated by synchronization (with no time lag), rapid and reactive mimicry

In an attempt to enhance the likelihood that a lie is perceived as truthful, deceivers might strategically attempt to build rapport in an interaction. Deceivers can build this rapport by coordinating behaviors with their interaction partners, thereby creating interpersonal synchrony. The goal of this study was to empirically test whether deceptive message senders strategically synchronize their behaviors

When it comes to health(-risk) behaviors, researchers are apt to consider how to change behaviors from a top-down approach (i.e., using the conscious, reflective, deliberate system) even though much of human behavior is determined by bottom-up processes (i.e., the nonconscious, reflexive, impulsive system). Given that researchers have proposed that interventions that target nonconscious processes underlying

The aim of the present study was to test the classic but under-researched hypothesis that individual differences in automatic emotional mimicry are positively related to individual differences in emotional contagion. To tap automatic mimicry and automatic emotional contagion, participants were exposed to affective stimuli with either a positive or negative valence (faces with a happy expression, n = 73;

Interlocutors make a variety of verbal and nonverbal adjustments to facilitate comprehension and enhance relational solidarity. This article examines research on vocal accommodation and mimicry as a specific subset of scholarship on nonverbal adjustments. We begin by introducing communication accommodation theory and discussing how accommodation is similar to and distinct from other related constructs

This study examined ways in which rhythmic features of movement contribute to bonding between individuals. Though previous studies have described synchrony as a form of social glue, this research extends those findings to consider the impact of fast versus slow tempo on movement synchrony. This two-part experiment examined dyadic interactions as they occurred between same-sex strangers (Study 1) and

Cooperation forms the basis of our society and becomes increasingly essential during times of globalization. However, despite technological developments people still prefer to meet face-to-face, which has been shown to foster cooperation. However, what is still unclear is how this beneficial effect depends on what people know about their interaction partner. To examine this question, 58 dyads played

This study presents a microanalysis of what information performers “give” and “give off” to each other via their bodies during a contemporary dance improvisation. We compare what expert performers and non-performers (sufficiently trained to successfully perform) do with their bodies during a silent, multiparty improvisation exercise, in order to identify any differences and to provide insight into

Emotions of other people cannot be experienced directly but are often inferred from a variety of verbal and nonverbal information, including expressive body movement (EBM). Inferring emotional states is critical in social interaction, and questions remain about the factors contributing to ambiguity of EBM. In addressing this issue, researchers have looked to the link between displayed arousal, or the

Deciphering others’ affect is ubiquitous in daily life and is important for navigating social interactions and relationships. Research has found that behavioral components, such as facial expressions or body language, are critical channels by which people understand other people’s affect. In the current research, we examined how people’s perceptions of targets’ positive affect (PA) and negative affect

Previous research has shown that in real-life situations people detect lies mostly from non-behavioral information (e.g., physical evidence, third-party information, confessions…) rather than from behavioral cues. Novotny et al. (J Nonverbal Behav 42:41–52, 2018. https://doi.org/10.1007/s10919-017-0263-2) argued that while lies are detected primarily from non-behavioral information, initial suspicion

Black, relative to White, individuals have experienced discrimination for centuries in the United States. Recent work suggests that subtle differences in how novel Black faces are initially perceived relate to prejudicial behavior. One such difference is that non-Black people attend more to the eyes of White versus Black novel faces. The present study sought to better characterize this difference by
